A mermithid nematode parasitic to larvae of Conogethes punctiferalis, a serious pest of ginger
and turmeric was recorded under field conditions during 2015 at Peruvannamuzhi (Kerala,
India). The infection reached epizootic levels during July to September 2015 exceeding 50%
mortality in host insect populations and the parasitism ranged from 18.2 to 80.6% and 17.9 to
66.7% in C. punctiferalis collected from ginger and turmeric, respectively. The level of host parasitism
by the mermithid was positively correlated with rainfall and negatively influenced by maximum
temperature. Molecular analysis of the partial 18S small ribosomal subunit gene region
and phylogenetic analysis with other mermithid sequences available in the GenBank indicated
that the present nematode clustered with other nematodes belonging to different genera and
hence could not be attributed to a specific genus. The pairwise Kimura 2-parameter (K2P) distance
revealed that the closest taxon to the study nematode was an undescribed mermithid species
reported to infect slugs with a K2P distance of 0.009. The epizootics caused by this
mermithid nematode in the natural populations of C. punctiferalis suggest its potential as a biocontrol
agent against a polyphagous pest of international importance. The results of our studies
provide a basis for using this nematode as a biocontrol agent for developing integrated pest
management strategies against C. punctiferalis.
